Design of stepping motor control system

Abstract

Based on the stepping motor principle and single-chip microcomputer control technology,hardware and software of the stepping motor control system have been designed.System uses discrete method realizing purpose of the precise control of stepping motor.Microcontroller uses STC12C5624AD.Step-motor drive chooses SH2034M model between the microcontroller and step-motor.Hall position sensor is installed in the stepping motor rotor realizing the stepping motor control system of closed-loop control.The software is presented on deceleration stepper motor speed control algorithm flow chart.Experiments show that the design of control system has the high control accuracy,good stability etc,and can be applied into unmanned robot system.
